Application filed February To ZZ 'whom it may conoci-n.'

Beit vknown that I, MiLLAnD F. HENNING, a citizen of the United States, residing at Gakland, in the county of Alameda and State of California, have invented a new and useful Improvement for Wlindow Screens, of which the following is a specification.

The invention relates to window screens, and more particularly to means whereby ordinary screens may be applied to and removed from windows An object of the invention is to provide new and improved fastening means for removably securing a window screen to a win dow sash.

Another object is to provide improved means for adjustably securing a screen to a window sash in such relation as to provide any desired degree of raising or lowering of the window sash.

Another object of the invention is to provide screen fastening devices that consist of a minimum of parts and which can be produced at a low cost.

Another object is to provide screen holders which constitute a guide for raising or lowering sashes and also to maintain the screen in proper' position.

W'ith these and other objects in view the invention consists in providing guide strips secured at one end to the window sashes and provided with guideways and portions eX- tending over the screen and holding the screen against the sashes or in the window frame to guard the desired opening.

The invention consists further in certain novel features of construction, arrangement and combination of parts as will be herein after set forth and claimed, reference being had to the accompanying drawing in which,

Figure 1 is an elevation of a window frame and its sashes, showing the invention as applied,

Figure 2 is a side elevational section,

Figurel 3 is a perspective view of the screen holder before attachment for use.

In the drawing 5 indicates an ordinary window frame in which arc mounted as usual the sashes S. n

The screen is indicated by the reference numeral G and comprises the conventional wire fabric and top, bottom and side rails 7 and 8 respectively.

The holders and fasteners comprise a pair of elongated flat plates or bars 9 offset adj arent one end 10 to provide the shoulder l1.

4, 1924. serial No. 590,676.

lThecomparatively short end portion 10 is provided with a key holeslot 12 .the pur pose of which willv later appear.`

The elongated` offset portion 9 is provided with an elongated narrow slot 13 which eX- tends from the free end to adjacent the shoulder 11. i

In applying the invention, it may be done in several ways, but I will now set forth one practical method: rIhe screen is put in place in the frame against the window sash, headed screws 14 are then placed in the side rails of the sash at such points as desired, and the keyhole slot 12 of the bars 9 passing over the heads of the screws the bars drop down with the straight part of the keyhole 12 embracing the shank of the screw and behind the head thereof the slotted portion of the bars lying against the screen frame; the screws 14: are now tightened up securely holding the bars in place. Screws 15 are now inserted through the slots and driven into the side rails of the sashes.

The device is now installed for usev and the screen can slide up and down with relation to the sashes, removed entirely therefrom or the sashes slid in relation to the screen; this latter operation is made possible by fastening the screens at either the top or bottom of window frame, such as by hooks and screw eyes 16 or other suitable coacting latching means.

The various parts of the device can be separated and stored, or packed in small compass for transportation, or the screen when once applied may be left on the sash, and adjusted to any position within the limits of its size and the length of the slot.

From the foregoing it is apparent that I produce an extremely simple, eiiicient and cheap device well adapted for objects in view, it being understood that such changes may be made as will fall within the scope of the4 appended claims.

Having thus fully described my invention and its application, what I claim is:

1. The combination with a window frame, window sashes and a screen, of screen holders comprising a pair of elongated plates oftset at one end and detachably secured at suchend to the window sashes, cooperating means carried by said plates and the screen for slidably maintaining the screen relatively to the sash, and cooperating latch means carried by an end rail of the screen and the window frame whereby the sashes llo may be raised or lowered to provide openings to be guarded by the screen.

2. The Combination with a window frame, Window sashes and u window screen, of a pair of slotted screen holding,l plates, Said plates otl'set und detaohably secured at one end to the side rails of the window sash, guide und binding pins secured to said screen und projecting through the slots of the pla-tes, and coaeting latch menne' carried by the end ruil of`r the screen ind the window frame.

3. The combination with. a Window frame,

Window sash and a Window screen of it pair of vertical bars having one end offset' inwardly and provided with a, keyhole slot in said offset portion, whereby to he removably attached to the side rails of the sash, said bars having elongated vertical slots therethrough, headed screws mounted on the sash and adapted to cooperate with said keyhole slots, and headed screws mounted on the side rails of the sash mid extending through said elongated slots.
